Yes it shifted to get better fuel mpg than the ecoboost. Funny people think if a trans shifts in and out that it must be weak. If that truck was put into 4th gear with cruise set it would have not shifted and then had equal fuel milage as ecoboost. GM programs trans to shift in and out to achieve best mpg.
